fil iSpeirlicati'oii forming-part ofiLetters Patent N ol 189,900,l dated.` AprilA 24,1877; application gfiled 4fDecexnber 27, 1876.

To all whom 'it may concern.- Y i Be it known that I, PETERMUNZINGER, of the city and county@ of Philadelphia, in the j State of Pennsylvania;havefinvented a new and useful Automatic Betort-Iilxhausterg of which I hereby declare the following to be a full, clear, and precise description, suflicient to enable those skilled in the art to which my improvement appertains to comprehend and employ it, reference being to the accompanying drawing, which forms part of this specification, and is a view in perspective of apparatus embodying my invention.

This improvement relates to exhausters for the retorts of gas-works which make use of a vacuum to effect the exhaustion; and has for its object the automatic regulation, by the flow of gas exhausted, of the formation of the vacuum, to the end that the formation of the vacuum and the iiow of gas may be regulated and controlled when the exhaustion becomes too great for the perfect generative powers of the retort, and a compensated or proportionate operation maintained.

It consists essentially as follows:

, A is the vacuum-chamber; B, the inlet-pipe to the same from the generating-retort; C, the escape-valve connecting the vacuum-chamber l and the escape-chamber D. E is the injectionpipe, by which the jet of water for the condensation ofthe gas to form the vacuum is admitted. F is an over-pressure pipe con# necting the vacuum-chamber A with a floattank, G, in which is, surrounded by water, a cylindrical open bottomed float, EI, beneath and inside of which the overpressure pipe opens. The float EI supports and operates a connecting rod and lever, I Z, connected with a supply-cock, J, on the injection-pipe, while it also supports and operates a rock-shaft and lever-arms, M, connected with the stem of the escape-valve C, all in such manner that when the float is elevated, the injection-cock J is turned on, and the escape valve C opened wide. K is a seal-chamber between the escapechamber and the main N leading to the washers and puriers, in which is located a liquid seal, L, to permit of the free passage of gas to the main, but prevent its return.I

I have represented a very simple system of 1- levers, M; betweeny iioat fand valvefconsisting lof a shaft, a, pivotedthrouglrtheifescape-chamberJ in such,` 'man nerI that .one `oflzits extremities extends outside, to whichV `sh-aftnaree -attached lever-arms, one `.of which-ztheioutsideb,l is connected with the float, and the otherthe insidee, with the valve-stem d, which is supported in a slide-bearing, e; but it is obvious that any system connecting the float and valve in such manner that when the iioat is lifted the valve is depressed, maybe employed. It

isalso obvious that a di'erent system of connections between the iioat and injection-cock may be adopted.

Such being the construction of my invention, its operation is as follows:

The lioat H, at the commencement of the operation, is down within its tank, and the injectioncock J and escapevalve O both closed.

The gas generated in the retort ows through the inlet-pipe B into the vacuum-chamber A, lling the latter, and then flows through the pipe F into the oat so as to lift it. By the rise of the float, through the medium of the lever-system I Z, theinjection-cock J is opened, so as to admit the injection water into the vacuum cham ber and open the escape -valve C, through the medium ofthe lever-system M depressed to the position indicated by the dotted lines in the drawing, opening it so as to permit the escape of the gas from the vacuum -chamber into the escape-chamber, and thence throughV the liquid seal to the main.

The injection, by condensing the gas in the chamber, pipe F, and float, forms a vacuum, and thus releaving the 'float H of its supporting agent, thereby permits said float to descend, so as to close the valve and shut off the injection, through the medium of the lever system described, thus leaving a vacuum in the vacuum-chamber, into which the gas from the retort is exhausted until said chamber is again lled with gas and the float again lifted to the repetition of the action described.

The above is-in some degree an exaggerated description ofthe action of my apparatus, for the sake of clearer illustration. In practice, the compensation is such that the flow of gas is practically continuous, and an absol quickly accumulating lute stoppage only effected when the exhaustion has been carried to an extent surpassing the perfect generative powers of the retort, to remedy which condition of things is especially the object of this my invention.

The advantage of my arrangement, therefore, lis that the apparatus constituting it is adapted to utilize, in the most effectual manner, the pressure of a too great expansion from the retort to the closing of the valve of egress, so as to give time for the evolving of a more perfect product from the charge in the retort, and is further adapted to the more perfect utilizing of an over-supply of gas, too in a chamber, to the raising of a float controlling both the injection and the valve of egress.

I do not claim, broadly, the utilization of an excess of exhaust gas from the retort for the raising of a oat to close the injection-valve of a vacuum gas-exhauster, to the automatic regulation of its action; but- What I do claim, and desire to secure by Letters Patent of the United States, is

l. In a vacuum-exhauster for retorts, the combination of a float, H, adapted to be elevated by an excess of gas in the valve-chamber A, with the injection-cock J, and with the escape-valve C, substantially as and for the purposes set forth. v

2. As a means of connecting the oat H with the injection-cock J and with the escapevalve C, respectively -the lever-system I, Z, and M, substantially as described.

In testimony whereof I have hereunto signed my name in the presence of two subscribing Witnesses.

PETER MUNZINGER.
